Acked-by: Arnd Bergmann <[EMAIL PROTECTED]> This one looks good, but I wonder if we should make it possible to also use it on QS20, which the current code doesn't allow. It's a rather hypothetical question, because QS20 has been replaced by QS21 as a product and it never supported PCIe cards with I/O space mappings, but it would be the "right" thing to do. Since you don't have the QS20 hardware to test that, and I currently doubt anyone at IBM has the energy to do the work, it will probably never get done. If you send another version of the patch, maybe you can add comments to hint that this is actually possible, just hasn't been implemented. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
